Abstract

A new silver(I) iodide cluster [Ag4I4(TMP)4] (TMP = tris(3-methylphenyl)-phosphine) 1 shows triply stimuli-responsive luminescent chromism, namely, mechano-, thermo- and solvent-responsive chromism, which is isostructural to our previously reported [Cu4I4(TMP)4] 2 but shows quite different luminescence in response to the external stimuli. Especially, during the mechanical grinding, the relative intensities of HE and LE of 1 varied with a concomitant hypsochromic shift, and when the temperature was decreased from 300 to 5 K, unprecedented contrary thermo-responsive trend for single crystal and powered samples (blueshift of single crystals and redshift of powdered samples) was observed. These distinct characters of 1 should be due to the different molecular packing modes, metallic interactions and the unique character of Ag(I) ion.
